Original application filed August 29, 1910, Serial No. 579,580. Dividedand this application filed August 1 16, 1915. Serial No. 45,777.

To all whom it may concern:

Be it known that I, ARTHUR L. RUssELL, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain Im provements in Apparatus for Use in theManufacture of Boots and Shoes, 'of which the following description,inconnection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

This invention relates to apparatus for use in the manufacture of bootsand shoes.

The object of the present invention is to provide an apparatus by whichinnersoles can be mounted on their lasts and secured thereon rapidly andaccurately and without the use of fastening tacks. I

One feature of the invention comprises a last having spurs, adapted tobe projected from the last bottom into an innersole, in lcombinationwith an innersole holder havmg means to sustaln the innersole againstthe thrust of the spurs.

, Another feature comprises a' last having spurs adapted to be projectedfrom the last bottom into an innersole, in combination spurs constructedto project into an innersole in combination with an innersole holderadapted to support the innersole against the thrust of the spurs andinconformity to the I t and forward turning of the heel partrelalongitudinal curvature of the last bottom.

A further feature of my invention comprises alast having spurs adapted'to be pro j ected into an innersole, in combination with an innersoleholder havlng supports for the of parts will be explained as thedescription proceeds, and will be pointed out in the claims.

The inventlon w1ll now be described 1n connection with a last of novelconstruction disclosed and claimed in my prior applicatoin Serial No.579,580, filed August 29, 1910, of which the present application is adivision, although it willbe apparent that the invention is not limitedto that or to any particular form of last.

In the drawings, which show a preferred embodiment of theinvention,Fig-ure 1 represents in section and side elevation a last l towhich an innersole has been attached acinnersoles on the new last. 1

The fore part of-the last is indicated at and the heel part at 4. Theheel part has n 1ts front face a plate 10 from which proect forwardlyand downwardly two'claws or hooks 12 adapted to extend into slots in thefore part and to hook over and in front of a cross bar 16 which issetinto the fore part just below the rearwardly inclinediedge of the forepart. The plate 10 also has forwardly directed fingers 14 which arelocated directly below the hooks 12 and-are spaced from the ends of saidhooks a distance slightly less than the width of the bar 16. Thesefingers have upper faces adapted to hook under the bar 16 after thehooks 12 have first been hooked over said bar and the heel part of thelast has been tipped from an upwardly and forwardly turned position downtoward its operat-ive position. The hooks and fingers thus embrace-thebarl6 to prevent any relative movement of the two parts of the assembledlast except the predetermined upward tively to the fore part. For thepurpose of restraining relative movement of parts 2 and l 4 except whenthe two parts are to be separated the heel part is provided with a'strut20 pivoted thereto, of-such a length as .to.

cause the lower end of the strut to wedge against 'the fore part of thelast and to lock the strut down by such wedging action. A friction faceplate 21 may be provided on the fore part for engagement bythe strut. Astop 22 is-located to prevent the strut from falling'too low and theheel part iSl cut away to permit the strut to be turned openings.

The fore part of the last is recessed longitudinally from its rear faceto receive the lever which is fulcrumedon a pin 26 and has therearwardly extending and inclined pivoted spur 28 and the oppositelyinclined pivoted spur 30. To the lever is also pivoted the connectingrod 32 which extends to and operates the rocker 3% which turns on pin 36and from which depends the for wardly inclined spur 35. The'bottom ofthe fore part has a metallic face-plate 40, which may be an inset plate,conveniently made of a suitable thickness of sheet metal formed withguide openings for the spurs 28, and 35. Guide flanges 12 for the spurscan be struck up in forming the guide The lever 25 has a convenientlyformed operating head shown as a let erally offset lip adapted to lieclose against the face of the rear end of the fore part when the leveris rocked to set the spurs wardly through the plate 40 and driven intothe innersole by a movement of the opcrating lever in one direction andto be retracted by reverse movement of the lever.

The heel part 4 may conveniently be used to engage the lip 45 for movingthe op erating lever to drive the spurs into the 111 nersole, said heelpart for this purpose being turned up to engage the 11p by impact, orpressure 1f preferred. In this way a sharp blow can, be struck on thelever to set the spurs firmly into the work. A holder 47 is provided inwhich the mnersoles will conveniently be arranged v1n stacks of assortedsizes and rights and lefts against pressed down upon the top of thestackwith its fore part also positioned against a toe end gage 48 and aside gage L9 as in Fig. 4:. The fore part of the last will be the gages.The holder comprises innersole supportmg members 56, 58 arranged underthe toe and ball and having curved upper faces to allow the innersolesto bend in accordance with the curvature of the last bottom. Eachsuchmember has positioning r of the operating lever to force thespursfingers to engage holes in the base to space said membersadjustably for different sizes of innersoles. After the fore part of thelast has been pressed down upon the top innersole of a stack sosupported the heel .part will be turned up to apply pressure, or

to strike a sharp blow, against the lip 45 One of said be thrust underthe lip 45 of lever 25 for retracting the lever if more force should berequired for doing that than an operator can conveniently apply with hisfinger or thumb. The strut 20 may convenbe arranged on the holder 47 asdescribet.

The last fore part will then be pressed firmly down upon. the topinnersole in the holder, the innersole and the last being bothpositioned against the gages 48, 49 to assure proper registration, andby then operating the lever 25 the several spurs will into theinnersole. It will be noted that the spurs are all arranged to bepro]ected outbe forced simultaneously into the inner face of theinnersole. The reverse inclination of the spurs provides againstdisplacement of the innersole lengthwise as the spurs are forced into itand prevents any longitudinal movement of the last fore part relativelyto the innersole while the spurs remain in engagement with theinnersole. The operation of the lever 25 may be effected by handpressure on the lip 45 and by pressing against or striking it with theheel part which can be turned for that purpose by the use of the tool 50if desired. The heel part of the last is then locked in extendedoperative position by the strut 20. Having positioned and secured theinnersole on the last bottom it is contemplated that the shoe will beassembled, pulled over, lasted, welted and outsoled as usual.Preparatory to the heel attaching operation the strut 20 may be loosenedand the heel part turned up and then lifted to remove it from the shoe,the tool 50 being again used, if de sired, for manipulating the heelpart. The fore part will be retained in the shoe and its longitudinalposition will be maintained by the fastening or bracing effected by thespurs and particularly by the spur 28.

When the shoe is completed the lever 25 will be manipulated to disengagethe spurs from the innersole and the last will be withdrawn from theshoe. The lip 55 of tool 50 may be used if desired to engage under thehead l5 of the lever for withdrawing the spurs.

The advantages of this invention will be apparent from the foregoingdescription.

The novel last disclosed herein forms the subject-matter of my parentapplication No. 579,580, filed August 29, 1910, and is not claimed inthis application. The novel method of making shoes disclosed is claimedin my application, Serial No.

@5778, filed August 16,1915, which is likewise a division of myapplication No. 579,580, and is not claimed in this application.
